Big Finish - 150 monthly releses

In August of this year Big Finish will have released it's 150th title in it's monthly line of Doctor Who audio dramas.This doesn't include the other series like the Benny stories or Eighth Doctor Adventures, Doctor Who Unbound, specials, etc...

This got me to thinking about my favorites.

These are some of my favorites (in no certain order):

Spare Parts - we see the return of original cybermen and Nyssa trying to stop their creation.

LIVE 34 - a unique play that presents a story in an unusual format, the adventures of the 7th Doctor, Ace and Hex brought through news broadcast.

The Chimes of Midnight - A murder-mystery where every time the clock chimes midnight, somebody dies.

The Juggernauts - The return of the Mechanoids.

Colditz - The introduction of Klien and the 7th Doctor and Ace imprisoned in Colditz prison.

Omega, Davros, Master - three stories that examine other aspects from these three characters.

That's all I'm doing for now but now I leave the question to you - what are your favorites?

EDIT: I forgot to mention that the reason this is is so small is because I've only gotten to #80 in the series but that number is quickly going up.

The Fifth Doctor story "The Kingmaker". Cracking story that gets better on repeat listenings. Plus, there are unexpected cameos, in-joke references -- it's great for the long-time fan without losing those new to the classic Doctor Who stories.
